Ferro Chrome

The addition of chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. Chromium is contained in many steels with special physicochemical properties. The chromium in the steel is added with ferrochrome. High carbon ferrochrome is used as an alloying agent for ball steel (0.5% to 1.45% Cr), tool steel, die steel (5% to 12% Cr) and high-speed steel (3.8% to 4.4% Cr) to improve the quenching of steel. Permeability increases the wear resistance and hardness of steel. The addition of chromium to cast iron improves hardness and improves wear resistance. Chromium-containing 0.5% to 1.0% improves mechanical properties. High-carbon ferrochrome and charge-grade ferrochrome are used in large quantities to smelt stainless steel (AOD or VOD method) to reduce production costs. Medium and low carbon ferrochrome is used to produce medium and low carbon structural steel, carburized steel, gears, high-pressure blower blades, valve plates, etc. Micro-carbon ferrochrome is used in the production of stainless steel, acid-resistant steel, heat-resistant steel, and electrothermal alloy.
